The polytetrafluoroethylene microporous membrane is produced using advanced biaxial stretching technology. The bonded material has a unique microporous structure, which is composed of hundreds of millions of continuous filaments arranged non-concentrically and crosswise. Microporous membrane.
Polytetrafluoroethylene microporous membrane, also known as ptfe bubble point membrane, is generally made of polytetrafluoroethylene (ptfe) suspended powder as raw material, and is expanded and stretched to form a microporous film.
It has a fibrillar microporous structure, the porosity can reach more than 88%, there are 1.4 billion micropores per square centimeter, and the pore size ranges from 0.1μm to 0.5μm.
Generally, this film is coated on various fabrics and substrates using special processes to become a new filter material.
Polytetrafluoroethylene is a polymer compound of tetrafluoroethylene. It is one of the materials with the best corrosion resistance in the world today. Except for a few chemicals such as chlorine trifluoride and liquid chlorine, it can withstand all other chemical reactions. It is insoluble in strong acid, strong alkali and organic solution, and does not change in boiling nitrohydrochloric acid.
The temperature resistance range is -195℃～250℃, and the long-term use temperature is -100℃～250℃.
